1990 Mazda B2200 Q&A
1990 Mazda B2200 Question: how to get the rpm and timing right without accelerating the engine too much??
put a ground wire from the green test connector.Set the rpm to 750 on idle and timing on 6. As soon I disconnect the ground wire,the engine accelerate and rpm goes over 800.The repair manual ask me to ground the test connector so i did.Just want to have my rpms right to smog check. Thanks. - juancarloslax
Are you setting the idle speed with the ground connected or just the 'base' timing? - ziptie12
